BRICK AND TILE MACHINE.

SPECIFIGATION'forming part of Letters Patent No. 276,544, dated April 24, 1883.

Application filed December 27, 1882. (No model.)

To all -whom it may concern I Be it known that I, GARRETT VAN WINKLE, of Avon, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements. in Brick and Tile Machines; and'I do hereby declare the following to be a full, clear, and exact description. of the invention', such as will. enable others skilled in the artto which it pertains to make and use the same. I

My invention relates to improvements in brick and tile machines; and it consists in the construction hereinafterdescribed and claimed.

In the drawings, Figure 1 is a side elevation view of a machine embodying my invention;

The object of my invention is toimprove and perfect a former device, for which Letters Patent No. 225,995'were granted, in March, 1879, to James W. Pentield, of Willoughby,

Ohio, and to which reference in this-specification is hereinafter made.

i 5 is an end view of the machine as adjusted for making large tile. Fig. 6 is an end view of the machine as adjusted for making small tile. Figs. 7, 8, 9, and 10 are views in detail, more fully hereinafter described.

Fig. l is an external view of the machine, showing the supporting-frame A, the legs a a, and also the casing B and B. The latter part of said casing is made detachable, and is provided with the hopper b. In this figure is also shown the spur-gearing for'operating the said machine. The gears (J and D are cooperative, and known as twin. gears. The. former is attached to the shaft 0, the latter to the shaft d, Fig. 2. To the shaftc are attached the pinion c', engaging with the gear E, and the pinion c engaging the gear G. To an extension of the shaft c.(not shown in the drawings) is attached a driving-pulley. To the shaft at is also attached the pinion d, engaging the gear F. The pinion 0 may be moved along the shaft 0 to the position shown in Fig. 2, so as to disengage the gear G, for purpose hereinafter shown. j

The continuation of the two respective shafts E and F forms the two respective puggingshafts, to which are attached spirally and radially the inclined tempering-blades, as at e and f. To the extreme end of these puggingshafts are attached respectively the feed-augers 0, 0 f, andf These feed-augers and tempering-blades on the two respective shafts are made respectively right and left handed, and the small feed-angers c and f are also made detachable and reversible interchangeably. The pugging-shafts are provided with the boxes a a and a a attached to the frame A, the latter being provided with set-screws and internal friction-plates for adjusting and receiving the end-thrust of the shafts, caused by the feed-angers and inclined tempering-blades. The said pugging-shafts are further supported by the boxes H and H. To these boxes are attached the tubes h and h. through supports on the frame A, and at this point are provided with adjusting orjam nuts, and by means of said tubes and said nuts the said boxes H and H are supported and adjusted laterally. To these tubes are also attached oilers, as at b, Fig. 1, for lubricating the said boxes H and H. These boxes are supported and adjusted vertically by rods attached to the bottom of the respectiveboxes. These rods, running through the outer casing, are secured by nuts to a support projecting from the frame A, (shown at h", Fig. 3.) I

The spur-gear Gr drives the hollow augershaft g, to which is attached the feed-auger Inside of said shat'tis the rod I, firmly attached at one end to the box c and holding andsupporting at the other end the core I ,in' a central position in the mold .1 The core I,

detachable. The direction of rotation in these angers is shown by the arrows in Fig. 4.

The machine as shown is in condition for making the large tile.

For making the smaller sizes of tile the gear G and c are disengaged, leaving the shaft g at rest. Theauger g is removed from the machine, as are also the core 1, the mold l and the plates K and K. (See Fig. 5.) The plate L, Fig. 7, is placed in position, as shown in Fig. 6, closing the top of the chamber in which the auger g revolves, the horizontal portion of the plate 0 resting on the shoulder O 0,

These tubes run the mold l, and feed-auger g are all made I do Fig. 4. In place of the plate K is substituted the plate L, containing the small-sized molds g and 9, Figs. 6 and 9. The cores J and J of these molds (shown in Figs. 10 and 6) are secured in a central position in their respective molds by being attached by screw-bolts j to the ends of the pugging-shafts. The size of these bolts and the size of the holes in the cores through which said bolts pass are relatively such that the bolts may freely revolve with the pngging-shafts whilcthe cores remain at rest. The molds g and 9 project back from said plate L to or beyond the end of the small feeding-angers e and f With this adjustment the machine is in condition to make the smaller sizes of tile.

By the use of reducing-bushings or liningplates for the molds, combined with proportionately smaller cores, the sizes of tile may be varied indefinitely.

The operation of my device is as follows: With the adjustment of the machine lastshown for making small tile the clay is fed into the hopper b, when, coming in contact with the tempering-blades of the respective pnggingshafts, itis thoroughly mixed or tempered and forced along and delivered to the said angers,

that in turn deliver the mixed clay to molds and force it through the annular orifice between the respective molds and cores.

In making the large tile the adjustment first described, and shown in Fig. 3,'is made. The small angers e and f however, are reversed and interchanged, so that instead of forcing the clay forward, as in case aforesaid, they press the clay backward toward the angers e and f. The result of the two sets of angers pressing toward each other is to force the clay down in contact with the large auger g, by which it is forced through the large mold aforesaid.

In the former machine aforesaid but one pugging-shaft was used, provided with a large feed-anger, infront of which was placed the mold for making the large tile. For making small tile the large mold was removed and a plate secured in its place. Two small angers were provided, operating in the chamber below, the said small angers receiving the clay from the large auger and forcing it through their respective molds, placed in front of them.

With the use of one pngging-shaft' it was found necessary, in order to obtain sufficient mixing or tempering capacity, to make the tempering-blades much longer than is necessary when two pugging-shafts are used, and also in the former device the clay, coming in contact with the entire circumference of the casing, offered great resistance as it was forced along toward the feed-angers. In my device but a portion of an entire circumference of casing for each pngging-shaft is thus exposed, a casing between said pugging-shafts being omitted. This admits of the free commingling of the clay as it is alternately acted upon by the blades of the respective pugging-shafts, and results in the clay being quickly and thoroughly tempered and freely and easily passed along to the feed angers aforesaid. Also, in the former device much power was expended by pressing the clay with great force against the plate infront of the large anger in the process of supplying clay to the small angers below. In my new device reversingand interchanging the small angers e and f, as aforesaid, obviates this difficulty and causes the clay to be freely and easily discharged to the large auger below. It will therefore be seen that by the operation of my new device a great economy of power and wear of parts is made as compared with the operation of the former device aforesaid.

What I claim is- 1. In a tile-machine, the combination, with two puggiug-shafts, each provided with tempering-blades and a feed-anger made respectively right and left handed, of two other feedangers made respectively right and left handed and interchangeable, and also so made that they may be reversed endwise on the shafts when interchanged, substantially as set forth.

2. In a tile-machine, the combination, with two pugging-shafts, each provided with tempering-blades and a feed-auger, of two other feed-angers extending more or less into the inner ends of the thimbles of theirrespective molds, substantially as and for the purpose shown and described.

3. In a tile-machine, the combination, with two pngging-shafts and their respective tempering-blades, of two feed-angers for each pugging-shaft, and so arranged that the rear angers will press the clay toward their respective front angers, and that the front au-- gers will press the clay toward their respective rear angers, resulting in relieving the front head from excessive pressure and of a free discharge of the clay to the' chamber below, substantially as and for the purpose set forth.

4. In a tile-machine, the combination, with two pugging-shafts and their respective feedangers, arranged and operated as heretofore described, of a feed-auger operating in a lower chamber receiving clay from the feed-angers above and forcing said clay through a mold in front of it, substantially as shown and de- IIO
